            [preview] => Array

            [preview] => Array

            [preview] => Array
                (
                    [boxshot] => upload/7/2/d_boxshot_72bb5a03708c99c822a792c76c00e8d1.jpg
                )

        )

)

我想返回一个访问每个preview的数组并获取内容

array('dvd-disc' => '...path...', 'dvd-cover' => '...path...', etc...)

请帮助，这是漫长的一天，我想回家！：）

修改

更正 - 我希望我的最终数组看起来像这样......

array(
    'dvd-disc' => '<img src="'.$path.'" alt="'.$type.'" />',
    'dvd-cover' => '<img src="'.$path.'" alt="'.$type.'" />', 
    etc...
);

其中$path是每个preview's子值的值，$ type是每个preview's子键的值

Answer 1

$new_array = array();
foreach($main_array as $sub_array)
{
   if(isset($sub_array['preview']))
   {
       foreach($sub_array['preview'] as $type => $image_url)
       {
           $new_array[$type] = '<img src="'.$image_url.'" alt="'.$type.'" />';
       }
   }
}

Answer 2

// (the array you are bring in is $mainArray)

// New array we'll be creating
$previewPaths = array()

foreach ($mainArray as $item) {

    foreach ($item['preview'] as $previewName => $previewPath) {

        $previewPaths[$previewName] = '<img src="'.$previewPath.'" alt="'.$previewName.'" />',;

    }

}
